Wacom pen input lagging in Photoshop CC 2015 on Windows 10

Wacom input in Photoshop CC 2015 (latest update) is buggy. Not each pen stroke is registered and sometimes the cursor turns into a "busy" icon while working with wacom pen input in PS. I've tried the older version of PS CC and other software like Mischief and Sketchbook, none of them have this problem. I work on a Cintiq 22HD and running the latest Wacom driver on Window 10.
